GRAINING DEVICE.

Specification of Letters Patent.

Application filed March 4, 1907. Serial No. 860,655.

rimmed April 27, 1909.-

.To all whom it may concern:

position as to insure non-interference, as for Be it known that I,ALBERT LYNN LAW- example, by placing them at an angle witl RENCE, acitizen of the United States of Amerioa,and a resident of Cleveland, inthe county of Cuyahoga and State of Ohio, have invented certain new anduseful Im rovements in Graining Devices, of which t e following is aspecification, having reference as 1 well to the accompanying drawings.

My invention relates to improvements in grain'ing devices, and has forits object the pgoduction of such an appliance-which shall of simple andcheap construction, durable and readily used by anyone withoutexperience.

This invention relates more particularly to a type of graining devicepossessing a flexible face, having a atter'n formed or molded thereon,adapte to be drawn or wiped over the surface to be grained, and. therebyproducing an irregular pattern resembling the desired'variety of wood.In such an appliance, however, it is desirable to combine in asingletool means for combing the pattern,

a tubular or cylindrical grainer, but the patrather than to resort to aseparate device, as has been done hitherto. I sirfableto apply two ormore graining patterns Moreover it is deto this style of grainer, and insuch manner that one will not interfere with the other. This generalresult. has been attempted upon terns necessaril 'are of short length,and

either lend litt e variation to the grained fisurface, or will'ii'iterfere with each other.

Such interference is not necessarily avoided so far as the comb isconcerned, since this device almost invariably is subsequently appliedto the grained-. attern. Again, itis hi hly desirable thatit shall beself-adaptab e to the graining of more or less irregular surfaces, andwhere the grainin surface is made of a high grade of soft rub er, asu'llioient body thereof will accomplish this result in some measure,but the cost of the comthe different patterns desired.

leted tool is thereby enhanced. Accordingl it has been my intent tocombine in a sing e, simple tool, all of the advantageous featuresindicated, while avoiding the objections inherent in prior devices.

Briefly stated, my improvements consist in providing a backingor frame,preferably of sheet metal, over which is suitably formed or riiolded'resilient graining face bearing These grainone another, Moreover, thesheet metal frame preferably is formed with spring fingers, or isotherwise rendered resilient, in order to make the device self-adapting,in

large measure, and the whole is mounted upon a suitable handle forconvenient manipulation. These, and other features, however, will bemore readily gathered by making reference to the accompanying sheet ofdrawings, wherein Figure I is a triangular graining tool embodying myinvention. the frame or metallic shell over which the Fig. IIillustrates graining face is molded' Fig. III is a section through saidshell or backing on line III-III. Fig. IV is a fragmentary view of thetool partially in section. Fig. V is a face view of one side the tool,partially broken away. Fig. VI is a top view of said tool, indicating byline I" the section shown in Fig. IV. Fig. VII is a top view uponsomewhat smaller scale of a modified form of .lIlY invention; a portionof the graining face being broken away.

Throughout each of 'the several figures I have employed the samecharacter Ofgdiglfifence to indicate similar parts. r

Preferably the device of my invention is .molded over a frame a of sheetmetal, such as shown in Figs. II or VII, for example; the same beingprovided with one or more curved surfaces formed of resilient orspring-like fingers, formed integrally with a body portion of the frame,which in turn is mounted upon the handle. A suit-ably shaped sheet metalframe formed of the gage of metal affording su llicient body forapplying the grain ing surface, ordinarily would present ,t 'r

polygon, as for example'the tween these lingers, lugs a may be formed,

which are bent u to assist in retaining the rubber in place, w iile theends of said fingers or teeth may likewise be slightly turn'ediip forthe same purpose, although this'j'i'snot r the necessary, particularlyupon small tools. The fingers maybe corrugated. as at a to strengthenthem somewhat, while in order to add to the resiliency, the corners ofthe metal v carded informing the "blank for constructing For example,'in the o small device or Fig. VIL, these curved spring my improveddevice.

- \fingers are arranged in parallel'planes upon elther side ofa narrowflattened connecting portion. The central handle I; is rigidly securedby .means of a screw 6, and embedded Washer 11 to" said supportingframe, as best shown in Fig. IV.

Thedisposition of the several patterns is optional, depending upon theparticular use for which the device is intended, but I have shown theemployment of four different patterns, c, d, e, and f, the latter beinga comb, While the others are arranged along the 2-5 curved sides of theframe. The covering or graining surface, preferably is molded from-athin sheet'of rubber directly upon the frame, although r1.1bber-compbsition, printers roller v composition, guttapercha and thelike,inay be utilized. Since the body :ef the rubber maybe relativelythin, however, the ex pense thereof is not great, and a grade of rubbermay inconsequence be used, which will resist alcohol, oils audthe like,without adding unduly to the cost. Graining pattern 0 is formed ofinterrupted or broken seg- 'ments, concentrically arranged and welladapted to simulate quartered oak. Pattern d is formed ofconcentric'ribs adapted for 40 simulating Georgia pine, and grainingpattern 2;, comprises a('* uteedged and generally 'conntric ribsadapted'fbr the imitation of oak, while the conical rubber points f mayadmirably be used in lieu' of the comb for finishing the graining.

' An extremely adaptable tool conforming to my invention, is shown inthe small view, Fig, VII, adapted to receive two graining 1 patternsalong corresponding curved surfaces, with an intermediate comb. Thisdeyiee is molded over the simple sheet steel frame a with the'rubbercovering its entire area, and supported thereby, and although atternsare relativelyadjacent, it will 5 be noted that the comb" isintermediate of these patterns. Inasmuch as the comb is almostinvariably applied, however, there s no opportunity for the one patternto interfere with the other, and this devicenot only is cheaper tomakabut is adapted for graining close to the edges of moldings andbaseboards, or over simple moldings. 'It will be understood, however,that'my improvements sizes, embodying more, or less'ofthe severa era asstric face in contact with the wet surface, and

forming the graining coat into a pattern 'resembling the desired varietyof Wood. .comb is then drawn over-"the grained surface, and with alittlepractice, close'imitations of different varieties of wood may beproduced by any user of my im roved tool. It will be seen that t e edgesof the graining patterns are unsupported, and by reason of theresilience of the metal, said patterns are rendered self-conforming toconsiderable variations in the grained'surface, without any attentionwhatever from the user. The sheet steel frame, however, permitssufficient pressure being applied, even with a large tool, 'to insureample contactbetween the graining pattern and the grained surface forwiping the graifiing coat into the semblance of a natural pattern of thedesired Wood; Inasmuch as the several graining patterns are disposedeither at an angle to one another, or oppositely and distantly ositionedupon the frame, there is no possibi ity, of one pattern interfering orblending intoanother when this device is used.

The pattern may occupy the entire or only a portion of the curvedsurface of the device, as indicated respectively upon the right and leftof Fig. VI.

Preferably a simple wooden handle b is centrally and rigidly-attached tothe frame, as indicated in Fig. IV, or by the dotted circle in Fig. VII, but any suitable handle obviously may be employed, since myinvention is not limited to the precise-means for practicing the same,herein set forth.
